I was going to sell 80% receivers for semi autos and post sample machine guns. Actually it is an 80% part that will make the gun fire. It consists of a ball of sting along with some nylon sleeves that you cut to length and then heat with a lighter to stop the ends of the string from fraying. I was about to send in a sample to the ATF for approval as an 80% when just the other day I dropped a load in my pants when I went to the store and saw 100% completed kits of what I was going to sell and believe it or not they were available in Wallymart. Actually all stores carry them in the shoe department. I guess somebody beat me to the production of them. I can't figure out how they are selling them to the public without Brady checks. I grabbed a whole bunch of them and they had them in all sorts of finishes, ie: black, white, flaurescent and crazily enough with Dora and Diego and Elmo pictures on them but what the heck. I threw them up on the counter with a weazily look on my face and dropped my concealed carry permit down for ID to purchase and the clerk just looked at me like I was crazy. Anybody else run into these type of fire control parts before?
